I've found a lot like that one but they're all pretty low quality - that one's two megapixel. Far cry from the iPhone's 12, despite being physically larger.

You're looking to take still photos? Because the 2 megapixel one would take video at 1080p.

I got a little SQ-11 camera with the same two-megapixel res and it generated truly awful imagery. I suspect the higher megapixel cameras generate better video even if they're squishing the data down to 1080p frame sizes.
